Summary
“I don’t get how you can smile, well rather…keep that facade up for as long as you have.”
“Unfortunately,” blinded eyes blink slowly, and head tilts marginally downward, “this is no facade.” Kagaya’s smile remains, words that felt somehow felt comfort despite the dismal tone of the word itself
“I don’t understand, there is no joy” the Flame Hashira’s dark brows furrow with mild frustration.
“Exactly.” Kagaya’s smile widens just the slightest, a genuine tell that rarely represents itself, finding something amusing

Kokushibo dons a mask to discreetly watch the progress of the broken man, he finds that he wants to keep that mask on forever when he begins to enjoy their time together… whilst Shinjuro unknowingly opens his fragile heart to a demon, Upper Moon One no less!
An inevitable betrayal comes forth, but for whom?

Summary
Shinjuro gets his medical license suspended since he was accused of committing malpractice. After finding a new, more fulfilling job—although paying him significantly less…suddenly the widower’s peaceful life gets a turn for the worse, when he finds out that his own father left him with a massive debt with the mob.
The collectors keep antagonizing him…and with no other options to provide the lofty sum within the time frame given…he finds himself working as a underground doctor for the same mysterious organization his father owed money to.
Coincidentally, years prior Shinjuro has made a lasting heart throbbing impression on the current head of the syndicate!
